Changed: redesigned program icon. Added 16x16, 48x48 dimensions.
Changed: speed of large text block selection is increased.
Changed: navigation through the Ctrl+Down/Ctrl+Up is now identical to RichEdit.

It's not of great consequence, but I thought I'd opine that I much prefer the style of the old icon to the new one. The new icon feels faded or weak -- even ghostly -- while the old one had a more bold, definitive look. The simple green is very attractive to me.
